DESCRIPTIO  
FEATURES  
The LTC®341±A is a high efficiency monolithic synchro-  
nous, step-down DC/DC converter utilizing a constant  
frequency, current mode architecture. It operates from  
an input voltage range of ±.±5ꢁ to 5.5ꢁ and provides a  
regulated output voltage from 0.8ꢁ to 5ꢁ while deliver-  
ing up to 3A of output current. The internal synchronous  
powerswitchwith77mΩon-resistanceincreasesefficiency  
and eliminates the need for an external Schottky diode.  
Switching frequency is set by an external resistor or can  
be synchronized to an external clock. 1002 duty cycle  
provides low dropout operation extending battery life in  
portable systems. ꢀPTI-LꢀꢀP® compensation allows the  
transient response to be optimized over a wide range of  
loads and output capacitors.

The LTC341±A can be configured for either Burst Mode  
operationorforcedcontinuousoperation.Forcedcontinu-  
ous operation reduces noise and RF interference while  
BurstModeoperationprovideshighefficiencybyreducing  
gate charge losses at light loads. In Burst Mode operation,  
external control of the burst clamp level allows the output  
voltage ripple to be adjusted according to the application  
requirements.
